Well hell with it. Now you don't even need functioning legs to drop my butt on the trail.
There's a Santa Claus look-a-like who drives around in my area on the model-T version of this sort of thing, but after more than a thousand miles I've never seen anything even remotely like this. Which is just as well. I don't need another class of people to go ripping past me like an F-18 on afterburner.
